License-free Backhaul Speeds Up

Posted by Sam Churchill on

Ubiquiti Networks has announced a new outdoor wireless backhaul radio platform called AirFiber. Their proprietary in-house radio design uses the license-free 24GHz band, and provides up to 1.4Gbps up to 13 km, without the capital costs associated with fiber. At $2,995 per link, it’s meant for wireless ISPs.

It features a dual-independent 2×2 MIMO 24GHz hi-gain reflector antenna system. AirFiber can operate in both FDD (Frequency Division Duplex) and HDD (Hybrid Division Duplex) modes for unparalleled speed and spectral efficiency in the 24GHz worldwide license-free band.

It features both TDD and FDD Operating Modes, with proprietary advanced HDD Operating Modes. Pre-Orders only available in the U.S. at this time.

Ubiquiti seems to be taking aim at DragonWave, a leading provider of high-capacity packet microwave solutions. FiberTower spectrum will bundled with DragonWave’s Avenue product line, enabling FiberTower’s 24 GHz and 39 GHz licenses to serve mobile carriers with six-inch and smaller antennas to provide street-level microcellular backhaul offerings.

SAF Tehnika radios cover spectrum 300MHz-38GHz and licence-free 17 and 24GHz with capacities up to 720Mbps full-duplex. SAF radios correspond to standards of ETSI, FCC and Industry Canada. Their 5.8 GHz product supports TDD technology and OFDM (with coding), providing actual Ethernet throughput of 100 Mbps (200 Mbps aggregated)

SAF Tehnika says that their SAF FreeMile Full Outdoor radios for Ethernet packet data and E1 voice transmission, operate in licence-free frequency bands of 17GHz and 24GHz. Their FreeMile 24 GHz full outdoor radios was provided a 100 Mbps full duplex network connection. SAF Tehnika is expanding its world reach of online shopping also to North American clients in early 2012.

Tower operators Crown Castle and American Tower, which previously created a joint venture in FiberTower, have merged with First Avenue Networks in a deal valued at approximately $1.5 billion. FiberTower will own 51 percent of the combined entity and have an installed base in 12 markets with more than 1000 sites

First Avenue Networks (above) bought out the radio spectrum assets of bankrupt of Advanced Radio Telecom (at 39GHz) and Teligent (at 24 GHz) and now has 24/39 GHz licenses throughout the United States with deep coverage in 77 metropolitan areas.

XO is one of the largest holders of fixed wireless licenses in the 28 GHz-31 GHz spectrum covering more than 70 U.S. major metropolitan markets. XO owns “the lion’s share” of A-band 28 GHz spectrum in the United States, as well as some B-band spectrum.

Other Gbps wireless gear is available from Alvarion, Bridgewave, Ceragon, DragonWave, E-Band Communications, Gigabeam, and Proxim’s GigaLink, among others.

Infonetics says the relatively small but fast-growing E-band (75–90 GHz) millimeter equipment market jumped 121% in 2010 to $69 million worldwide.

The Dell’Oro Group 5-Year Forecast Report offers an overview of the Microwave Transmission industry with tables covering manufacturers’ revenue, average selling prices, radio transceiver shipments, and port shipments for TDM Microwave, Packet Microwave and Hybrid Microwave systems by capacity.

Maravedis predicts the BWA/WiMAX subscriber base will reach approximately 28.6 million at the end of 2012. This year, operators are spending $3 billion to install LTE base stations and related equipment, according to ABI Research. By 2016, they forecast annual LTE spending will be $16.5 billion.

One thought on “License-free Backhaul Speeds Up

  1. As mentioned above, there are several manufacturers that have made point-to-point wireless gear in the unlicensed 24 GHz band. One notable product that has recently been introduced is the Trango StrataLink 24 from Trango Systems. The StrataLink 24 is a carrier-class microwave backhaul product which features longer link distances than previously available due to the narrow channel sizes and exceptional system gain. Users are able to select between eight channel bandwidths from 10 to 60 MHz and nine modulations from QPSK to 1024QAM.

    The Trango StrataLink 24 is able to reach 750 Mbps full duplex in a 60 MHz channel bandwidth (1.5 Gbps aggregate capacity). Using XPIC/2+0 this unlicensed 24 GHz wireless backhaul product is capable of reaching 1.5 Gbps full duplex (3 Gbps aggregate capacity). The StrataLink 24 also features two GigE ports for traffic and in-band management, one of which is SFP. The SFP port allows flexibility because it can be used with single-mode fiber, multi-mode fiber or copper. Power is provided by PoE or direct power. The StrataLink 24 is an industrial strength backhaul radio built for the most extreme weather conditions with a durable cast alloy construction. The extended temperature range of -40° to 149° F / -40° to +65°C makes the Trango StrataLink 24 well suited for deploying in harsh environments.
